My research seeks to unite theoretical neuroscience and linguistics at the level of computation. Brains are incredibly powerful yet restricted types of computers at every level, from dendrite trees to single neurons to neuronal networks. Human languages are also remarkable in their generative power, yet constrained by strong computational principles at every level, from syntax to morphology to phonology. I attempt to connect the computations that neurobiological networks can perform with the computations required by human grammars, in order to generate the incredible variety of languages we see.
Humans intuitively pattern meaningless symbolic elements into meaningful units when we comprehend and produce language. The rules and structures governing this patterning - phonology - act as a cognitive filter for the underlying structure of language as it is transformed into external action, whether through speech, sign, or tactile language. The wide variety of patterns that humans produce across languages, and their mappings from underlying forms to surface forms, show a remarkable computational simplicity, combined with efficient and accurate learning algorithms. I draw on automata theory, formal language theory, grammatical inference, and mathematical logic to clarify the nature of the human mental capacity of phonology.

Phonology lies at the intersection of linguistics and neurobiology. Phonological rules govern the physical instantiation of thought made in language, and yet phonology is the first completely abstract computational layer that perceptual encoding/decoding must enter. The mapping problem, or instantiating these symbolic rules into neuronal systems, is an important part of figuring out the biological capacity for language. How brains perform this feat is a matter of their unique structure and computing power, most of which is an open question.
